This is an unvented gas-fired heater. It

uses air (oxygen) from the room in which

it is installed. Provisions for adequate com-

bustion and ventilation air must be pro-

vided. Refer to page 4.

WARNING: If not installed, operated and

maintained in accordance with the manu-

facturer's instructions, this product could

expose you to substances in fuel or from

fuel combustion which can cause death or

serious illness.

WATER VAPOR: A BY-PRODUCT OF

UNVENTED ROOM HEATERS

Water vapor is a by-product of gas

combustion. An unvented room heater

produces approximately one (1) ounce

(30ml) of water for every 1,000 BTU's

(.3KW's) of gas input per hour. Refer to

page 4.

• Installation and repair should be done by a QUALIFIED

SERVICE PERSON. The appliance should be inspected

before use and at least annually by a professional service

person. More frequent cleaning may be required due to

excessive lint from carpeting, bedding materials, etc. It is

imperative that control compartments, burners and circu-

lating air passageways of the appliance be kept clean.

• DO NOT use this room heater if any part has been under

water. Immediately call a qualified service technician to

inspect the room heater and to replace any part of the

control system and any gas control which has been under

water.

• Due to high surface temperatures, keep children, clothing

and furniture away.

• An unvented room heater having an input rating of more

than 10,000 Btu per hour shall not be installed in a

bedroom or bathroom.

• Due to high temperatures, the appliance should be

located out of traffic and away from furniture and drap-

eries.

• Children and adults should be alerted to the hazard of

high surface temperature and should stay away to avoid

burns or clothing ignition.

• Young children should be carefully supervised when they

are in the same room with the appliance.

• Do not place clothing or other flammable material on or

near the appliance.

WARNING

When used without adequate combustion and ventilation

air, heater may give off CARBON MONOXIDE, an odor-

less, poisonous gas.

Do not install heater until all necessary provisions are

made for combustion and ventilation air. Consult the

written instructions provided with the heater for infor-

mation concerning combustion and ventilation air. In

the absence of instructions, refer to the National Fuel

Gas Code, ANSI Z223.1, Section 5.3 or applicable local

codes.

This heater is equipped with a PILOT LIGHT SAFETY

SYSTEM designed to turn off the heater if not enough fresh

air is available.

DO NOT TAMPER WITH PILOT LIGHT SAFETY

SYSTEM!

If heater shuts off, do not relight until you provide fresh air.

If heater keeps shutting off, have it serviced. Keep burner

and control compartment clean.

CARBON MONOXIDE POISONING MAY LEAD TO

DEATH.

Early signs of carbon monoxide poisoning resemble the flu,

with headache, dizziness and/or nausea. If you have these

signs, heater may not be working properly. Get fresh air at

once! Have heater serviced.

Some people — pregnant women, persons with heart or

lung disease, anemia, those under the influence of alcohol

, those at high altitudes — are more affected by carbon

monoxide than others.

The pilot light safety system senses the depletion of oxygen

at its location. If this heater is installed in a structure

having a high vertical dimension, the possibility exists that

the oxygen supply at the higher levels will be less than that

at the heater. In this type of application, a fan to circulate

the structure air will minimize this effect. The use of this

fan will also improve the comfort level in the structure.

When a fan is used to circulate air, it should be located so

that the air flow is not directed at the burner.

by point with the members of your household. Someday

when there may not be a minute to lose, everyone's safety will

depend on knowing exactly what to do. If, after reading the

following information, you feel you still need more informa-

tion, please contact your gas supplier.

Propane (LP-Gas) is a flammable gas which can cause fires

and explosions. In its natural state, propane is odorless and

colorless. You may not know all the following safety precau-

tions which can protect both you and your family from an

accident. Read them carefully now, then review them point

SAFETY INFORMATION FOR USERS OF LP-GAS

LP-GAS WARNING ODOR

If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.

That's your signal to go into immediate action!

• Do not operate electric switches, light matches, use your

phone. Do not do anything that could ignite the gas.

• Get everyone out of the building, vehicle, trailer, or area. Do

that IMMEDIATELY.

• Close all gas tank or cylinder supply valves.

• LP-Gas is heavier than air and may settle in low areas such

as basements. When you have reason to suspect a gas leak,

keep out of basements and other low areas. Stay out until

firefighters declare them to be safe.

• Use your neighbor's phone and call a trained LP-Gas service

person and the fire department. Even though you may not

continue to smell gas, do not turn on the gas again. Do not

re-enter the building, vehicle, trailer, or area.

• Finally, let the service man and firefighters check for

escaped gas. Have them air out the area before you return.

Properly trained LP-Gas service people should repair the

leak, then check and relight the gas appliance for you.

Some people cannot smell well. Some people cannot smell

the odor of the chemical stench put into the gas. You must

find out if you can smell the odorant in propane. Smoking can

decrease your ability to smell. Being around an odor for a time

can affect your sensitivity or ability to detect that odor. Some-

times other odors in the area mask the gas odor. People may not

smell the gas odor or their minds are on something else. Think-

ing about smelling a gas odor can make it easier to smell.

The odorant in LP-gas is colorless, and it can fade under

some circumstances. For example, if there is an underground

leak, the movement of the gas through soil can filter the odorant.

Odorants in LP-Gas also are subject to oxidation. This fading

can occur if there is rust inside the storage tank or in iron gas

pipes.

The odorant in escaped gas can adsorb or absorb onto or into

walls, masonry and other materials and fabrics in a room. That

will take some of the odorant out of the gas, reducing its odor

intensity.

LP-Gas may stratify in a closed area, and the odor intensity could

vary at different levels. Since it is heavier than air, there may be

more odor at lower levels. Always be sensitive to the slightest

gas odor. If you detect any odor, treat it as a serious leak.

Immediately go into action as instructed earlier.

NO ODOR DETECTED - ODOR FADE

• Learn to recognize the odor of LP-gas. Your local LP-Gas

Dealer can give you a "Scratch and Sniff" pamphlet. Use it

to find out what the propane odor smells like. If you suspect

that your LP-Gas has a weak or abnormal odor, call your LP-

Gas Dealer.

• If you are not qualified, do not light pilot lights, perform

service, or make adjustments to appliances on the LP-Gas

system. If you are qualified, consciously think about the odor

of LP-Gas prior to and while lighting pilot lights or perform-

ing service or making adjustments.

• Sometimes a basement or a closed-up house has a musty

smell that can cover up the LP-Gas odor. Do not try to light

pilot lights, perform service, or make adjustments in an area

where the conditions are such that you may not detect the

odor if there has been a leak of LP-Gas.

• Odor fade, due to oxidation by rust or adsorption on walls of

new cylinders and tanks, is possible. Therefore, people

should be particularly alert and careful when new tanks or

cylinders are placed in service. Odor fade can occur in new

tanks, or reinstalled old tanks, if they are filled and allowed

to set too long before refilling. Cylinders and tanks which

have been out of service for a time may develop internal rust

which will cause odor fade. If such conditions are suspected

to exist, a periodic sniff test of the gas is advisable. If you

have any question about the gas odor, call your LP-gas

dealer. A periodic sniff test of the LP-gas is a good safety

measure under any condition.

• If, at any time, you do not smell the LP-Gas odorant and you

think you should, assume you have a leak. Then take the

same immediate action recommended above for the occasion

when you do detect the odorized LP-Gas.

• If you experience a complete "gas out," (the container is

under no vapor pressure), turn the tank valve off immedi-

ately. If the container valve is left on, the container may draw

in some air through openings such as pilot light orifices. If

this occurs, some new internal rusting could occur. If the

valve is left open, then treat the container as a new tank.

Always be sure your container is under vapor pressure by

turning it off at the container before it goes completely empty

or having it refilled before it is completely empty.

Water Vapor: A By-Product of Unvented Room Heaters

Water vapor is a by-product of gas combustion. An unvented room

heater produces approximately one (1) ounce (30ml) of water for every

1,000 BTU's (.3KW's) of gas input per hour.

Unvented room heaters are recommended as supplemental heat (a room)

rather than a primary heat source (an entire house). In most supplemental

heat applications, the water vapor does not create a problem. In most

applications, the water vapor enhances the low humidity atmosphere

experienced during cold weather.

The following steps will help insure that water vapor does not become a

problem.

1. Be sure the heater is sized properly for the application, including

ample combustion air and circulation air.

2. If high humidity is experienced, a dehumidifier may be used to help

lower the water vapor content of the air.

3. Do not use an unvented room heater as the primary heat source.

Provisions for Adequate Combustion and Ventilation Air

This heater shall not be installed in a confined space or unusually tight

construction unless provisions are provided for adequate combustion and

ventilation air.

The National Fuel Gas Code, ANSI Z223.1 defines a confined space as a

space whose volume is less than 50 cubic feet per 1,000 Btu per hour

(4.8m

per kw) of the aggregate input rating of all appliances installed in

that space and an unconfined space as a space whose volume is not less

than 50 cubic feet per 1,000 Btu per hour (4.8m

per kw) of the aggregate

input rating of all appliances installed in that space. Rooms communicat-

ing directly with the space in which the appliances are installed, through

openings not furnished with doors, are considered a part of the unconfined

space.

The following example is for determining the volume of a typical area in

which the SR-30T may be located and for determining if this area fits the

definition of an unconfined space.

The input of the SR-30T is 30,000 Btu per hour. Based on the 50 cubic

feet per 1,000 Btu per hour formula, the minimum area that is an

unconfined space for installation of the SR-30T is 1,500 cubic feet, 50

cubic feet x 30 = 1,500 cubic feet. To determine the cubic feet of the area

in which the SR-30T is to be installed, measure the length, width and

height of the area. Example: The area measures 16 feet in length, 12 feet

in width and 8 feet in height, the area is 1,536 cubic feet. The SR-30T can

be installed in this unconfined space with no requirement to provide

additional combustion and ventilation air.

Warning: If the area in which the heater may be operated is smaller than

that defined as an unconfined space or if the building is of unusually tight

construction, provide adequate combustion and ventilation air by one of

the methods described in the National Fuel Gas Code, ANSI Z223.1,

Section 5.3 or applicable local codes.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough fresh

air for combustion and ventilation. However, in buildings of unusually

tight construction, you must provide additional fresh air.

Unusually tight construction is defined as construction where:

a. Walls and ceilings exposed to the outside atmosphere have a

continuous water vapor retarder with a rating of one perm or less

with openings gasketed or sealed, and

b. Weatherstripping has been added on openable windows and

doors, and

c. Caulking or sealants are applied to areas such as joints around

window and door frames, between sole plates and floors, between

wall-ceiling joints, between wall panels, at penetrations for plumb-

ing, electrical, and gas lines, and at other openings.

If the SR-30T heater is installed in a building of unusually tight

construction, adequate air for combustion, ventilation and dilution of

flue gases shall be provided in accordance with ANSI Z223.1/NFPA54.

Compounds used on threaded joints of gas piping shall be resistant to the

action of liquefied petroleum gases. The gas lines must be checked for

leaks by the installer. This should be done with a soap solution watching

for bubbles on all exposed connections, and if unexposed, a pressure test

should be made.

Never use an exposed flame to check for leaks. Appliance must be

disconnected from piping at inlet of control valve and pipe capped

or plugged for pressure test. Never pressure test with appliance

connected; control valve will sustain damage!

A gas valve and ground joint union should be installed in the gas line

upstream of the gas control to aid in servicing. It is required by the

National Fuel Gas Code that a drip line be installed near the gas inlet.

This should consist of a vertical length of pipe tee connected into the gas

line that is capped on the bottom in which condensation and foreign

particles may collect.

Figure 10

Method of Installing a Tee Fitting Sediment Trap (Figure 10)

The use of the following gas connectors is recommended:

— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing

and Fittings

— ANS Z21.45 Assembled Flexible Appliance Connectors of Other

Than All-Metal Construction

The above connectors may be used if acceptable by the authority having

jurisdiction.

Pressure Testing of the Gas Supply System

1. To check the inlet pressure to the gas valve, a 1/8" (3mm) N.P.T.

plugged tapping, accessible for test gauge connection, must be

placed immediately upstream of the gas supply connection to the

appliance.

2. The appliance and its appliance main gas valve must be discon-

nected from the gas supply piping system during any pressure testing

of that system at test pressures in excess of 1/2 psig (3.5 kPa).

3. The appliance must be isolated from the gas supply piping system

by closing its equipment shutoff valve during any pressure

testing of the gas supply piping system at test pressures equal to

or less than 1/2 psig (3.5 kPa).

Attention! If one of the above procedures results in pressures in excess

of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will result

in a hazardous condition.

Checking Manifold Pressure

Natural gas will have a manifold pressure of approximately 6.0" w.c.

(1.49kPa) at the pressure regulator outlet with the inlet pressure to the

pressure regulator from a minimum of 7.0" w.c. (1.743kPa) for the

purpose of input adjustment to a maximum of 10.5" w.c. (2.615kPa).

Propane/LP gas will have a manifold pressure approximately 10.0" w.c.

(2.49kPa) at the pressure regulator outlet with the inlet pressure to the

pressure regulator from a minimum of 11.0" w.c. (2.739kPa) for the

purpose of input adjustment to a maximum of 13.0" w.c. (3.237kPa).

A test gage connection is located downstream of the gas appliance

pressure regulator for measuring gas pressure. The connection is a 1/8

inch (3mm) N.P.T. plugged tapping.

High Altitudes

For altitudes/elevations above 2,000 feet (610m) ratings should be

reduced at the rate of 4 percent for each 1,000 feet (305m) above sea

level. Contact the manufacturer or your gas company before changing

spud/orifice size.

Piezo Pilot Ignitor Instructions

Depressing the ignitor button completely causes a spark to occur at the

pilot.

To light the pilot, it is important that the electrode be 1/8" (3mm) from

the pilot. The spark must occur at the point the pilot flame hits the

thermocouple.

On a new installation with air in the gas line, it is suggested that a match

be used. The match will light the pilot faster than the piezo under this

condition.

Keep appliance area clear and free from combustible materials,

gasoline and other flammable vapors and liquids.

SR-10T, SR-18T and SR-30T Main Burner Flame (Figure11)

The main burner flame will have a red-orange glow over the surface of

the ceramic plaques. A few small, hairline cracks may form over the

surface of the ceramic plaques or at the edges of the ceramic plaques

where they have been cemented into position on the burner assembly

frame. These small, hairline cracks will not affect the operation or

performance of the ceramic plaques. Only, when large cracks develop,

with blue flames escaping from the large cracks, should you contact your

QUALIFIED SERVICE PERSON.

A red-orange haze that is visible on the ceramic plaques is acceptable.

A blue flame that rolls out at the top of the ceramic plaques indicates an

accumulation of dust, lint or spider webs inside the casing assembly and

main burner assembly. Use the following procedure to inspect the casing

assembly and main burner assembly.

1. Turn OFF gas supply to the heater.

Figure 11

Proper Pilot Flame (Figure 12)

The correct flame will be blue and will extend beyond the thermocouple.

The flame will surround the thermocouple just below the tip. A slight

yellow flame may occur where the pilot flame and main burner flame

meet.

Figure 12

Oxygen Depletion Sensor Pilot (Figure 13)

When the pilot has a large yellow tip flame, clean the Oxygen Depletion

Sensor as follows:

1. Clean the ODS pilot by loosening nut B from the pilot tubing. When

this procedure is required, grasp nut A with an open end wrench.

2. Blow air pressure through the holes indicated by the arrows. This

Warning:

Never use needles, wires, or similar cylindrical objects to clean

the pilot to avoid damaging the calibrated ruby that controls the

gas flow.

Thermostat Operation

To ignite main burner, turn gas control knob counterclockwise toward

HI setting. To shut down main burner, turn gas control knob clockwise

toward LO setting.

The SR-10T has an input of 10,000 BTUH (2.9KW/H). The hydrau-

lic thermostat bulb is located at the casing assembly bottom. When

the hydraulic thermostat bulb senses the need for heat, the unit cycles

“ON” at a full input rate of 10,000 BTUH (2.9KW/H). The unit

remains at this full input rate until the hydraulic thermostat bulb is

“satisfied.” When the hydraulic thermostat bulb is “satisfied” the

burner will shut “OFF” with the pilot flame remaining “ON.”

The SR-18T has an input of 18,000 BTUH (5.3KW/H). The hydrau-

lic thermostat bulb is located at the casing assembly bottom. When

the hydraulic thermostat bulb senses the need for heat, the unit cycles

“ON” at a full input rate of 18,000 BTUH (5.3KW/H). The unit

remains at this full input rate until the hydraulic thermostat bulb is

“satisfied.” When the hydraulic thermostat bulb is “satisfied” the

burner will shut “OFF” with the pilot flame remaining “ON.”

Note: The burner does not modulate between “ON” and the pilot

flame. When the SR-18T is “ON,” all three ceramic plaques will

“glow.” There will never be a time when only one or two ceramic

plaques are “glowing.”

The SR-30T has an input of 30,000 BTUH (8.8KW/H). The hydraulic

thermostat bulb is located at the casing assembly bottom. When the

hydraulic thermostat bulb senses the need for heat, the unit cycles "ON"

at a full input rate of 30,000 BTUH (8.8KW/H). The unit remains at this

full input rate until the hydraulic thermostat bulb is "satisfied." When

the hydraulic thermostat bulb is "satisfied" the burner will shut "OFF"

with the pilot flame remaining "ON."

Note: The burner does not modulate between "ON" and the pilot flame.

When the SR-30T is "ON," all five ceramic plaques will "glow." There

will never be a time when only one or three ceramic plaques are

"glowing."

The LO and HI setting has temperature range of approximately 55°F

(12.78°C) to 90°F (32.22°C), respectively. This is the temperature at the

hydraulic thermostat bulb not the room temperature. The owner is

advised to determine the particular heat setting that is desired for

comfort, as heating requirements are different for every owner.

Attention: If the owner does not want the main burner to ignite and

turns the gas control knob to the LO setting, the main burner will still

ignite if the temperature at the hydraulic thermostat bulb drops to 55°F

(12.78°C).

If no heat is desired, turn the gas control knob to the PILOT position.

FOR YOUR SAFETY READ BEFORE LIGHTING

WARNING: If you do not follow these instructions exactly, a fire or explosion may result

causing property damage, personal injury or loss of life.

A. This appliance has a pilot which must be lighted by

hand. When lighting the pilot, follow these instructions

exactly.

B. BEFORE LIGHTING smell all around the appliance

area for gas. Be sure to smell next to the floor because

some gas is heavier than air and will settle on the floor.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electrical switch;

do not use any phone in your building.

• Immediately call your gas supplier from a neigh-

bor's phone. Follow the gas supplier's instructions.

• If you cannot reach your gas supplier, call the fire

department.

C. Use only your hand to push in or turn the gas control

knob. Never use tools. If the knob will not push in

or turn by hand, don't try to repair it; call a

qualified service technician. Force or attempted

repair may result in a fire or explosion.

D. Do not use this appliance if any part has been under

water. Immediately call a qualified service techni-

cian to inspect the appliance and to replace any part

of the control system and any gas control which has

been under water.

3. Push in gas control knob slightly and turn clock-

wise to "OFF". Do not force.

TO TURN OFF GAS TO APPLIANCE

1. Set thermostat (gas control knob) to lowest setting.

2. Turn off all electric power to appliance if service is to be

performed (if applicable).

LIGHTING INSTRUCTIONS

to hold the control knob in for about one (1) minute

after the pilot is lit. Release knob and it will pop

back up. Pilot should remain lit. If it goes out,

repeat steps 4 through 8.

• If knob does not pop up when released, stop and

immediately call your service technician or gas

supplier.

• If the pilot will not stay lit after several tries, turn

the gas control knob to "OFF" and call your

service technician or gas supplier.

9. Attention! Gas control has an INTERLOCK latching

device. When the pilot is initially lit and the safety

magnet is energized (pilot stays "ON") the INTER-

LOCK latching device becomes operative. If the gas

control is turned to the "OFF" position or gas flow to

the appliance is shut off, the pilot cannot be relighted

until the safety magnet is de-energized (approxi-

mately 60 seconds). There will be an audible "click"

when the safety magnet in the gas control is de-

energized. Pilot can now be relighted. Repeat steps

4 through 8.

10. Turn gas control knob counterclockwise

to "HI".

11. Turn on all electric power to appliance (if applicable).

12. Set thermostat (gas control knob) to desired setting

from "HI" to "LO".

1. STOP! Read the safety information above.

2. Set thermostat (gas control knob) to lowest setting.

3. Turn off all electric power to the appliance (if appli-

cable).

4. Push in gas control knob slightly and turn clockwise

to "OFF". Do not force.

5. Wait ten (10) minutes to clear out any gas. Then smell

for gas, including near the floor. If you smell gas,

STOP! Follow "B" in the safety information above. If

you don't smell gas, go to the next step.

6. Find pilot - the pilot is

attached at the bottom of

the burner assembly .

7. Turn gas control knob

counterclockwise to "PILOT."

8. Push in gas control knob all the way and hold in.

Repeatedly push the piezo ignitor button until

pilot is lit (or use a match to light pilot). Continue

supplied with the appliance

must be replaced, it must be

replaced with type 125°C wire

or its equivalent.

Wiring

The appliance, when installed, must be electrically grounded in accor-

dance with local codes or, in the absence of local codes, with the

National Electrical Code, ANSI/NFPA 70, if an external electrical

source is utilized

. This appliance is equipped with a three-prong

[grounding] plug for your protection against shock hazard and

should be plugged directly into a properly grounded three-prong

receptacle. Do not cut or remove the grounding prong from this plug.

For an ungrounded receptacle, an adapter, which has two prongs and a

wire for grounding, can be purchased, plugged into the ungrounded

receptacle and its wire connected to the receptacle mounting screw. With

this wire completing the ground, the appliance cord plug can be plugged

into the adapter and be electrically grounded.

CAUTION: Label all wires prior to disconnection when servicing

controls. Wiring errors can cause improper and dangerous opera-

tion. Verify proper operation after servicing.

Blower Motor

The blower motor does not have oiling holes. Do not attempt to oil the

blower motor.

Blower Wheel

The blower wheel will collect lint and could require periodic cleaning. If

the air output decreases or the noise level increases, it indicates a dirty

blower wheel.

To clean blower wheel:

1. Turn OFF gas supply to the heater.

2. Turn OFF electrical supply to the heater.

3. Remove lower louver from casing assembly (2 screws).

4. Remove reflector from casing assembly (2 screws).

5. Remove upper louver from casing assembly (2 screws).

6. Clean blower wheel with a vacuum cleaner.

7. As parts are being replaced in reverse order, check for gas leaks at all

gas connections before lower louver is replaced onto casing assembly.
